It's not working is not enough information! Why is it not working? Syntax, logic. Are you getting errors? If not you should be.

I have taken a look at your code and given the sparse detail on your error I am assuming you want the test to happen at every elseif level - whilst elseif will nest, the first elseif expression (if any) that evaluates to TRUE would be executed only - If I have got the wrong end of the stick supply additional info on your problem..

Is categori a constant or a variable? Should it be $categori instead?
